WebOct 15, 2024 · Solubility is the basis for judging whether inorganic salts can crystallize and deposit from water. Based on the solubility comparisons of different salts under different conditions, it's convenient to discuss the interaction among different kinds of salts and analyze their crystallization and deposition characteristics. WebCrystallisation is the process of formation of solid crystals from solution, melt or by deposition directly from a gas phase. Crystallisation is obtained through a variation of the solubility conditions of the solute in the solvent, by opposition to precipitation that is due to a chemical reaction.

The crystallization process consists of two major events, nucleation and crystal growth which are driven by thermodynamic properties as well as chemical properties. Nucleation is the step where the solute molecules or atoms dispersed in the solvent start to gather into clusters, on the microscopic scale (elevating solute concentration in a small region), that become stable under the current operating conditions. These stable clusters constitute the nuclei. Therefore, the clusters … WebSolubility Study Guide Pdf Pdf ...
